ATOMdesign was asked by Vaughan & Bushnell to re-imagine the classic hammer and the S2 is what they came up with.

ATOMdesign didnâ€™t take the challenge lightly. They not only delivered a revolutionary new hammer design but secured a U.S. utility Patent with 27 claims! The Split-Head hammer offers many new features never seen before in the industry such as integrated overstrike plates, modular head construction, and elastomeric shockgaskets just to name a few.

But the real question remains: if I hit somebody over the head with it will I still go to jail? Because that's my number one complaint with traditional hammers.
